About this image

Total of 3.5-hours integration taken on 10th and 11th October 2021.

Just out of shot (bottom left) is gamma-cassiopeia (Navi).  It is the energising radiation from Navi that is creating both the red emission 'comet nebula' and being scattered by molecular dust to create the blue reflection nebula.  IC59 and IC63 also known as the Ghost Nebula or Gamma-Cassiopea Nebula.
